    Df(3R)dsx2M/Df(3R)Scx2 is pupal lethal. Df(3R)dsx2M/Df(3R)Scx2 mutants also exhibit an apparent failure of body wall muscle contraction during puparium formation.

    Inferred to overlap with: Df(3R)dsx2M.

    Inferred to overlap with: Df(3R)Mlp84BP8.

    Df(3R)Scx2/Df(3R)Scr embryos have defects in head involution.

    Df(3R)Scr2/Df(3R)MAP2 viable Df(3R)Scr2/Df(3R)MAP2 pb phenotype

    NOT in combination with other aberrations

    Revertant for the 'Scx' phenotype (extra sex combs on the meso- and metathoracic legs).

    Homozygous lethal.
